Application filed. February 12, 1917. Serial No. 148,287.

between the inner and the outer hull of the vessel for closing anopening in the inner hull, caused by a collision, thereby arresting aflow of water into the hull.

A further object of the invention is to provide a plurality of shiftableelements capable of being interposed between the outer and inner hull ofaship for the purpose of reinforcing said innerhull to prevent damagethereto by collision.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts, ashereinafter more specifically de scribed and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes,variations and modifications canbe resorted to which come within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout'the several views Figure 1 is a perspective view of aportion of the inner and outer hull of a vessel showing the adaptationof a-leak stopper associated with the innerhull.

Fig. 2 is a front elevation of a portion of a leak stopper.

Fig. 3 is an end view of a portion of said leak stopper with thecoupling between the rolls removed.

Fig. 4 is an end view of a portion of said leak stopper with thecoupling means between the rolls in position.

Figs. 5 and 6 are diagrammatical views illustrating the manner ofshifting theleak stoppers.

Referring to the drawings in detail 1 denotes the outer and 2 the innerhull of a vessel and interposed therebetween are spaced bracing elements3 in the form of T-irons. The elements 3 are secured to the inner faceof the outer hull l and the outer face of the inner hull 2, by securingdevices as at 4, 5.

The brace members 3 conform in contour to the shape of the hull invertical section and each lateral flange of each brace member, at theinner end of saidbrace member, is formed with a lengthwise groove 6,extending from end to end ofthe brace member and capable of beingshifted in a pair of opposed grooves 6 is a leak stopper constituting acombined reinforcing and sealing element for the inner hull 2.

A leak stopper is arranged between each pair of brace members 3 and whennot in, such position they are arranged in guide grooves, not shown,formed in the bottom of the deck. The stoppers are not, when inoperative position, of a height equal to the height of the hull, but areabout one-half to two-thirds of the height of the hull.

The stoppers are to be arranged, when in an operative position, at eachSide of the hull and when not in operative position stored in the guidegroove of thefloor of the deck; the stoppers employed on one side of thevessel are arranged below the stoppers employed on the other side of thevessel. Each' of the stoppers has connected to its upper end a pair ofelevating cables 7, which are adapted to wind upon the longitudinalshaftarranged in the guide groove in the deck referred to. lVhen the shaft 8is operated in one direction all of the stoppers are elevated and housedin the recess in the floor of the deck. A shaft 8 is employed inconnection with one side of the hull and a shaft 8 employedfor thestoppers in connection with the other side of the hull.

Each of the stoppers has its lower end for lowering the stoppers andsaid cables 9,

of the elements employed for both sides of the ship, wind on a singleshaft 10 which is arranged at the keel.

Each of the stoppers consists of a plurality of rolls 11 and a pluralityof filler members 12. The rolls 11 are alternately disposed with respectto the filler members 12 and each of the latter has curved seats 13, 14,against which seat a pair of rolls 11.

Each of the rolls 11, at each end has a pintle 15, provided with areduced end 16. The enlarged portions of the pintle 15 travel againstthe side walls of the groove ("3. Each lit] llll'l of the tiller membershas its end provided with a shaft 17 of the same diameter as the theywill act as a reinforcing means and furthermore if an opening has beenformed in the inner hull 2- by a collision, then by lowering theelements they will act as a sealing means and interrupt the passage ofwater into the hull.

7 hat I claim is 1. An attachment for marine vessels comprising thecombination of members interposed between the inner and outer hulls ofthe vessel, each of said members in the form v of I-beam and each havingthe flange at the inner end thereof grooved, of a combined reinforcingand sealing member capable of being shifted against the outer face ofthe inner hull and extending into a pair of opposed grooves.

2. An attachment for marine vessels comprising the combination ofmembers interposed between themner and outer hulls of the vessel, eachof said members in the form of Ibeam and each having the flange at theinner end thereof grooved, of a combined reinforcing and sealing membercapableof beingshifted against the outer face of the inner hull andextendlng into a pair of op- JOSBCl grooves, said element consistin ofal h i i b ternately disposed rolls and filling members, means; forcoupling sald fillermembers and rolls together, said coupling meanssliding the opposed grooves, means for elevating and loweringsaidelement.

3. An attachment for marine vessels comprlsing a combinatlon with anmner and outer hull and spaced bracing members between sa d hulls, theinner ends of said bracing members provided with opposed grooves, of acombined reinforcing and sealing member capable of shifting in saidgrooves, to a position at the front. of the inner hull, and means forelevating and lowering saidselemeat.

Copies bf this, patent may be obtained for i it An attachment for marinevessels comprising a combination with an inner and outer hulland-spacedbracing members between said hulls,-the inner ends of saidbracing members provided with opposed grooves, of a combined reinforcingand sealing member capable of shifting in said grooves to a position atthe front of the inner hull-,and means for elevating and lowering saidelement, said element consisting of alternately disposed rolls andfilling members coupled together at their ends. I

5. An attachment for marine vessels comprising a combined reinforcingand sealing element adapted to be positioned between the outer and the.inner hulls of the vessel, said element consisting of alternatelydisposed rolls and filler members, said filler members having seatsagainst which bearsaidrolls, and means connected to the GDClS'Of saidrolls a and filling members 7 for connecting them to gether.

6. An attachment for marine vessels comprising a combinedreinforcing andsealing member for the hull of a vessel, said element consisting ofalternately disposed rolls and filler members coupled together at theirends.

7,. An attachment for marine vessels comprising the combination withpairs of op posed grooves arranged within the hull, of a combinedreinforcing and sealin element slidably mounted in each pair of opposedgrooves, means connected with one end of said element for elevatingitfromwithin the grooves, and meansconnected ,to the, lower end of theelement for lowering it to a position within-the grooves, each of saidelements consisting of alternately disposed rolls and filler memberscoupled together at their ends. Y

In testimony whereof I affix my signature in the presence of twowitnesses.
